The UK introduced the Corporate Interest Restriction (CIR) as a key tax law in 2017. This policy aims to cap the interest expense that businesses can subtract from their taxable income. The goal is to make sure companies pay their fair share of tax in the UK. If you run a business in the UK, you must grasp what the CIR means for you and how to handle its rules.
Understanding the purpose and scope of the CIR
The UK government brought in the CIR to make the country’s tax system match up with the Base Erosion and Profit Shifting (BEPS) project, which the Organisation for Economic Co-operation and Development (OECD) leads. The CIR’s main goal is to stop big companies that work in many countries from using too many interest deductions to move profits out of the UK and pay less tax overall.
The CIR is applicable to UK-resident companies and UK permanent establishments of non-UK resident companies. It covers many financing arrangements such as loans, overdrafts, finance leases, and certain derivatives. These rules aim to ensure businesses can deduct a specific amount of their net interest expense, based on a percentage of their taxable earnings before interest, taxes, depreciation, and amortisation (EBITDA).
Key provisions and rules of the CIR
The CIR’s key provisions and rules include:
- Interest Deduction Limitation: The CIR restricts the amount of net interest expense that a business can deduct from its taxable income to the greater of:
- 30% of the company’s taxable EBITDA, or
- £2 million.
- Group Ratio Rule: The CIR also allows for a group ratio rule, which can increase the amount of interest a company can deduct. This rule depends on the ratio of the group’s net interest expense to its accounting EBITDA.
- Carry-forward and Carry-back of Disallowed Interest: Any interest expense that the CIR disallows can be used in future periods subject to the same interest deduction limits. Companies can carry this interest forward.
- Reporting and Compliance: Companies must report their interest expense, EBITDA, and other key data to HM Revenue & Customs (HMRC) in their yearly tax returns.
How the CIR affects UK businesses
The CIR can impact UK companies especially those with high debt or large interest costs. Some main effects include:
- Less tax-deductible interest expenses result in higher taxable profits and a bigger tax bill overall.
- The push to change financing structures to maximise interest deductions allowed under CIR rules.
- Tax planning and compliance grow more complex calling for expert knowledge and tools.
- This could affect how companies invest and the cost of borrowing money.
Getting through the CIR: What you need to do and report
Following the CIR rules can be tricky and takes a lot of time. Companies must keep close track of their interest costs, EBITDA, and other key info to tell HMRC. This might mean:
- Finding all the relevant money deals and working out the net interest cost.
- Figuring out the company’s taxable EBITDA and using the 30% limit.
- Checking if the group ratio rule might apply.
- Keeping thorough records and paperwork to back up the calculations for interest deductions.
- Filing the company’s yearly tax return on time.
If a business doesn’t follow the CIR rules, HMRC might impose fines and take other enforcement steps.
Ways to handle and maximise interest deductions under the CIR
To deal with the CIR’s effects and get the most out of interest deductions, companies might think about these approaches:
- Debt Restructuring: Looking at current debt setups and changing them to reduce the net interest expense that falls under CIR limits.
- Financing Mix Optimisation: Looking into other ways to finance, like equity financing or using hybrid instruments, to cut down the overall interest expense.
- Group Ratio Rule Optimisation: Looking at the group’s money situation and using the group ratio rule to boost the available interest deduction.
- Carry-forward and Carry-back of Disallowed Interest: Keeping a close eye on the carry-forward and carry-back of disallowed interest to make the most of its use in future periods.
